Type: Dromaeosaurid theropod dinosaur.

Age: Early Cretaceous (127 to 124 million BC; Late Barremian to Early Aptian)
Episode: Giant of the Skies
Info: The largest of the so-called “raptor” dinosaurs, or dromaeosaurids, Utahraptor was the size of an ice cream truck, the weight of a polar bear, the hip height of a full-grown man, and a killing toe claw 10 inches long. It was described in 1993, the same year Steven Spielberg’s blockbuster Jurassic Park was released in theaters and was thought to be an inspiration to the film’s raptors, but much bigger: 
"Later, after we had designed and built the Raptor, there was a discovery of a Raptor skeleton in Utah, which they labeled 'super-slasher'. They had uncovered the largest Velociraptor to date - and it measured five-and-a-half-feet tall, just like ours. So we designed it, we built it, and then they discovered it. That still boggles my mind”
-Jody Duncan, in the Making of Jurassic Park.

Note: So here's the original version up above and the feathered version! I am going to do the same thing with most of the other dinosaurs that appear in this great documentary mini-series! 

On April 2, 2017, I re-did the updated version of the dinosaur and based it on a recently done skeletal artwork done by and in honor of
